How Evaporative Coolers Work
The first thing to know is how Evaporative Coolers, or swamp as some call them, work. This is important to recognize because it will make the difference in what type of Cooler you purchase and where it is placed. All Coolers produce cool air the same way. As water is pumped over the pads or media it is evaporated into the air. This evaporation process causes a temperature drop of the discharged air. The more water absorbed into the air, the greater the temperature drop of the discharged air. Humid air is already saturated with moisture, therefore you will get far less temperature drop across the cooling media. In very dry areas much more water can be absorbed into the air. This causes a temperature drop from the outside air to the discharge air of 20 to 30 degrees. Swamp Coolers use about 25% of the energy that an air conditioner will use. They can be a very economical choice in the drier areas.
Stationary Or Portable Cooler?
Many prefer to use a roof mounted or a window mounted Cooler. These usually provide cooler air, but both require installation. A roof mounted Cooler requires a roof stand, roof penetration, and a duct system in your attic. This will cost you several thousand dollar just for the installation. A window mounted Cooler is much less expensive, but a separate unit is required in each room to cool the house. Both of these types of Coolers draw in outside air. This dry outside air moving across the cooling media is cooler than air being recirculated continuously through a Portable Cooler. As the air becomes more humid in the room, less water can be absorbed when the air passes through the media. Because of this it is better to position the Portable Cooler in or close to a door or a window. mccoy cooler
There are advantages that Portable Coolers give which you do not have with other types of Coolers. A roof mounted Cooler is more difficult to access and maintain. It also cools the house with a larger motor that uses more energy. This is not necessary if only one or two rooms of the house are used at a time. Window Coolers are more accessible but are too difficult to move from room to room. Portable Coolers are perfect for moving to different areas of the home when needed.
Which Portable Evaporative Cooler Model Should I Purchase?
There are several manufacturers that make quality Portable Coolers. Tradewinds makes several models that are versatile as well as quality products. They currently have five models in their Gadabout series. The Tradewinds M500 is their largest model and is generally used in areas like workshops and garage areas. The Tradewinds M150, Tradewinds M201A, Tradewinds M301A, and Tradewinds M401A are all Portable Coolers perfect for residential use. These models all vary in size and CFM discharge (Cubic Feet of air per Minute). Champion also produces several quality Portable Evaporative Coolers. They produce three stylish pedestal design Coolers. These are Champion CP35, Champion CP65, and the Champion CP70. Many people like these models because of their oscillating louvers. The Champion EC302 is a model shaped similar to a box fan. This model can be rolled on it’s casters or set on a stand in front of a window.
